"Movement of Enhancing Opportunities and Improving Technology", abbreviated as Fatih, is among the most important educational projects in Turkey, which students teachers can use their tablet PCs to obtain data (text, images, media, etc.) stored cloud servers. However, limited network bandwidth increase both number users sizes degrade system performance even negatively affect overall usability system. Proxy server a solution approach decreasing traffic increasing efficiency transfers between...
In this study, field-programmable gate array (FPGA)-based hardware implementation of the wavelet neural network (WNN) training using particle swarm optimization (PSO) and improved (iPSO) algorithms are presented. The WNN architecture activation function approach that is proper for suggested in study. Using algorithms, test operations implemented on two different dynamic system recognition problems. From results obtained, it observed generalizes well has approximately same success rate with...
There are no large-scale deployments to navigate the people indoor environments as GPS for outdoor environments. For this reason, development of high-performance systems localization has been considered potential research areas by both academia and industry in last decade. These studies divided into two groups literature which readerbased tag-based systems. Most these reader-based. readers tags can determine received signal strength levels using radio frequency technology. We present a...
The number of multi-storey building complex is increasing every day. Nowadays, widely used in the navigation system's position open space provided by Global Positioning Satellite System GNSS. Unfortunately, direct use GNSS systems indoor areas not possible. Many technologies field location determination (Wireless, RF(Radio Frequency), Bluetooth, ...) have been used. This article aims to develop a minimal cost positioning system. proposed system avoid (to capture minimum cost) RSSI (Received...
In modern computer systems (communication systems, military medical applications, etc.) are sophisticated mathematical operations and trigonometric calculations widely used. CORDIC (Coordinate Rotation DIgital Computer) architecture should be used on digital computers to implement complex calculations. this study, two architectures called FP-CORDIC IQ-CORDIC have been devised algorithm. These realised with IEEE-754 IQ-Math in order. Also they compared according execution time, process...
FFT/IFFT is the most important module for OFDM based baseband Wimax Modem architecture. However, computational complexity of this larger compared to other blocks in an system.

Tekstil sektöründe, mamul kumaş üzerindeki üretim hatalarının tespiti, kalite kontrol aşamasında yapılan en önemli ve maliyetli işlerdendir. Kumaşlar konfeksiyon aşamasına gelmeden edilir hatalı kısımlar kumaşın içinden parça halinde kesilerek alınır. Bu durum fireye yani üretimde düşüşe yol açmaktadır. Eğer esnasında fark edilememiş veya alımı ile ayırılamamış kusurlar varsa bu kumaşlarda ikinci kaliteye düşmektedir. Kalite sonrası top kesim işleminde ayrılan kumaşlar edilmeyerek müşteriye...
